Ankle is swolen and painful

Patient: My left ankle, which I had reconstructive surgery on about 8 years ago, has swelled up and is painful to walk on. I started walking/running at lunch again on Monday and think that may have been what aggravated it. Is this a time when I listen to my body and stay off of it (I am icing and elevating already) or push through the pain and get out there to walk at lunch?

Symptoms: Pain and welling
